WAGON-SPRING BUFFER.

SPECIFICATION forming part of Letters Patent No. 430,770, dated June 24,1890.

Application filed October 30,1889. Serial No. 328,681. (No model.)

T0 all whom it ntay concern.-

Be it known that 1, AUGUST G. FISCHER, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented certain new and useful Improvements inWagon- Spring iuft'ers; and I do declare the following to be-a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to theletters of reference marked thereon,which form a part of thisspecification.

Myinvention relates to buffers, and has for its object the provision ofa buffer attached to wagon-springs to prevent the tail-board fromstriking the spring-head when the tailboard is released and swung down.

The invention consists in a spring-head provided with a buffer, ofrubber or other elastic material, which projects beyond the head of thespring and receives the stroke or concussion of the tail gate or boardwhen the latter is swung down.

The simplest form of embodying the in vention consists in forming a holethrough the face of the spring-head and passing a rubber buffer havingan enlarged butt through said opening from the inside before the head isfixed upon the spring. Such form of embodiment is shown in theaccompanying drawings, 'wherein Figure 1 is a side elevation of the rearend of a wagon, showing the buffer applied to a spring. Fig. 2 is a sideelevation of the end of the spring on an enlarged scale, showing thebuffer. Fig. 3 is a plan view of Fig. 2. Fig. 4 is a plan view of thehead and butter removed from the spring. Fig. 5 is an end elevation ofthe head, and Fig. 6 is a longitudinal section of Fig. 4.

Similar letters of reference indicate corresponding parts in all thefigures where they occur.

A A are the leaves of the springs.

13 is the head of the spring, applied in the usual way, and O is thebuffer. The head B is provided with a tapering hole I), and its face maybe carried out into the sides I) I),

thus giving a long firm grip upon the buffer C, which, as shown,'has atapered butt c,and is passed through the opening I) from the in side ofthe head before the head is set in place. I The end of the spring abutsagainst the inner end of the buffer and holds it in place, while theouter end of the buffer projects beyond the face of the spring-head andreceives the tail-board when it swings down, as shown in Fig. 1. buffermay be applied to the end of the spring in different Ways; but thatshown in the drawings I believe to be the best.

Instead of having the buffer set in the head It is evident that the ofthe spring, it may be held in a detachable one end of the long leaves,provided with an opening through the end thereof, and a buffer passedthrough said opening from the interior and abutted against the end ofthe leaves, as set forth.

3. A vehicle-spring having ahead covering one end of the long leaves andprovided with the extended sides I) b and tapering opening l), in'combination with a buffer C, having a tapering butt 0', substantially asand for the purpose set forth.

In testimony whereof I affiX my signature in presence of two witnesses.

AUGUST G. FISCHER.
